Explanation

Microwaves are defined as electromagnetic radiations with a frequency ranging between 300 MHz to 300 GHz.

In contrast, the wavelength ranges from 1 mm to around 30 cm.

Microwave radiation is commonly referred to as microwaves.

They fall between infrared radiation and radio waves in the electromagnetic spectrum.

*********

 Magnesium does in nitrogen at room temperature

Titanium does but at a higher temperature  something like 800C.

Explanation

Air is a mix of gases, with nitrogen (78%) and oxygen (21%) being the main components.

The plus trace amounts of other gases like argon, carbon dioxide, and water vapor.

Explanation

The most available form of solid fuel is wood. Wood is obtained from the trees and when trees die and decomposed for years through is called coal.

Explanation

• Aluminium, Magnesium, and Iron are all metals that are commonly used in construction and building materials.
• Including in the manufacture of cars, bridges, and houses.

Explanation

Hydrogen has 3 Neutrons. 

Explanation

Trees release carbon dioxide at night and carbon dioxide being heavier than air descendes.So a person sleeping under a tree breathes carbon dioxide which is harmful for the human body.

Explanation

The device that is used to measure temperature is called Thermometer .

Temperature measurement (also known as thermometry) describes the process of measuring a current local temperature for immediate or later evaluation. 

Explanation

The ozone layer is a thin part of the Earth's atmosphere that absorbs almost all of the sun's harmful ultraviolet light. "Ozone holes" are popular names for areas of damage to the ozone layer.

Explanation

A fluorescent lamp consists of a glass tube filled with a mixture of argon and mercury vapour.
